Dallas Braden defends his decision not to have the Blue Jays in the top five of the power rankings, while Tim Kurkjian explains why Toronto deserves a top-five spot. (1:50)

The Chicago Cubs roll on at No. 1 for another week, a spot it doesn't appear they'll give up anytime soon. The Washington Nationals remain No. 2 for another week, but they're getting pushed by the Texas Rangers, who jumped to No. 3 this week and received second-place votes.

The Los Angeles Dodgers jumped from No. 10 to No. 8 and are closing in on the San Francisco Giants (No. 6) in both the rankings and the National League West. The Dodgers still don't have Clayton Kershaw back, Rich Hill hasn't pitched for them yet, and Brandon McCarthy (right hip stiffness) and Brett Anderson (wrist) left their starts over the weekend, but they've managed to stay afloat in the playoff race.

Elsewhere in the rankings, the Seattle Mariners jumped four spots, from No. 16 to No. 12, after winning five of six games.

After a series split with the Cardinals, caused primarily by bullpen blowups, watch for the Cubs to make two moves before rosters expand on Sept. 1: One to reach out to Jonathan Papelbon, given the familiarity with Theo Epstein, and one to add a left-handed bench bat to counteract the Tommy La Stella standoff. -- Joe Aiello (@VFTB), View from the Bleachers

Shoutout to Wilson Ramos, who continues to rake with a .332/.379/.541 line. Ramos had Lasik surgery in early March, after a career-worst 2015 season, and has cut his strikeout rate from 20 percent to 12.9 percent. Also: Jonathan Papelbon was released. -- David Schoenfield (@dschoenfield), SweetSpot

Texas, likely to finish with 90 or more wins for the fifth time in the past seven seasons, looks to be in the driver's seat in the AL West. The keys will be getting the starting rotation healthy and keeping veterans fresh down the stretch. -- Brandon Land (@onestrikeaway), One Strike Away

Late last week, the Indians received the disappointing news that Michael Brantley will not play again this season. This bad news was tempered somewhat by a four-game sweep of the Angels, in which the Indians outscored the Halos 37-12. In Friday's 13-3 win, the Tribe stole eight bases, which tied a franchise record. -- Stephanie Liscio (@stephanieliscio), It's Pronounced Lajaway

J.A. Happ's past seven starts: 6-0, 1.25 ERA, 43 1/3 innings, 28 hits allowed, 55 strikeouts. His 3.4 WAR to this point in the season is his best mark since he compiled a 4.0 figure with the Phillies in 2009. Aaron Sanchez, having already tossed a career-high 152 1/3 innings this year, will have at least a couple of starts skipped over the next six weeks. -- Diane Firstman (@dianagram), Value Over Replacement Grit

Joe Panik was a well-above-average player in 2015, as he slashed .312/.378/.455 with strong defense at second. In the first half this season, his line was down to .256/.321/.407, and since his return from the DL, his batting line is just .184/.293/.224. -- Jeff Wiser (@OutfieldGrass24), Inside the 'Zona

A three-run blast by Jonathan Schoop capped a comeback victory over the San Francisco Giants in the Orioles' final game on the West Coast this season. Schoop's tater salvaged an otherwise disappointing series of games in California, which included dropping three of four to the Oakland A's. The O's remain a half-game behind Toronto and get an off-day before they play eight straight games at home. -- Matt Kremnitzer (@mattkremnitzer), Camden Depot

Los Angeles sits right behind the Giants for the division lead, despite its middle-of-the-road offense (homers and OPS-wise) and horrific list of pitcher injuries. The depleted pitching staff suffered two more hits over the weekend when Brandon McCarthy and Brett Anderson each left their starts with injuries. -- Diane Firstman (@dianagram), Value Over Replacement Grit

Could it have been Boston that picked up the most dominant reliever this July? After three strikeouts with the bases loaded and no outs Saturday, Brad Ziegler's batting average against with the Red Sox dropped to .229. -- Ryan P. Morrison (@ryanpmorrison), Inside the 'Zona

This was a tough week, as Michael Wacha and Matt Holliday both landed on the DL. Wacha has a shoulder issue that could sideline him the rest of the season, and Holliday suffered a fractured thumb after getting hit by a pitch. -- ESPN.com

If the best the Tigers can do is limp into a one-game, sudden-death playoff game, they might be best served to buck veteran experience and give the opportunity to Michael Fulmer, who has allowed three runs or fewer in 14 of his past 15 starts. -- Richard Bergstrom (@rbergstromjr), Rockies Zingers

After releasing Carlos Gomez and with Colby Rasmus on the DL, the Astros are trying to win with a makeshift outfield that includes Tony Kemp, who played mostly second base in the minors, and Teoscar Hernandez, who was called up after hitting .307 with 10 homers in the minors. -- David Schoenfield (@dschoenfield), SweetSpot

With Giancarlo Stanton possibly out for the remainder of the season, Miami has Alex Rodriguez under consideration. Also, the team isn't expecting Wei-Yin Chen back anytime soon.

Gerrit Cole has allowed nine earned runs in his past 10 innings, and since starting the season 5-3 through May 26, he has pitched to a 2-5 record. A 4.04 ERA over that span, however, is hardly a disaster. -- Ryan P. Morrison (@ryanpmorrison), Inside the 'Zona

The new-look Yanks sandwiched a pair of losses around four straight wins this week, a week that saw a rather clumsily handled end to Alex Rodriguez's career. In his place arrives a bevy of youngsters, including behemoth Aaron Judge (home runs in first two games). With the team barely clinging to hopes of a wild-card berth, all eyes are firmly forward to 2017 and beyond.-- Jason Rosenberg (@Jason_IIATMS), It's About the Money

Neil Walker is leading MLB with a .444 batting average since July 27; he has two doubles, one triple, five home runs, 13 RBIs and 12 runs scored in that span (18 games). Prior to 2016, Walker had six career homers vs. LHPs. This year, he has hit seven off lefties.

Charlie Blackmon has twice as many home runs in August (eight) as the Rockies have wins (four).

It has been a down year for Jose Abreu, who followed 5.3 and 3.0 WAR seasons with a minus-0.3 WAR effort in the first half of 2016. He has seemed to find his footing since the All-Star Break, however, as he is hitting .306 with a .359 OBP in his past 27 games. -- Ryan P. Morrison (@ryanpmorrison), Inside the 'Zona

Alex Dickerson, Travis Jankowski and Jabari Blash have thrived since San Diego dealt Matt Kemp at the trade deadline. The Padres now have a three-rookie outfield.

What a mess. The Angels have now lost 10 in a row after the Indians swept a four-game series by a score of 37-12. The team's current .419 win percentage would be the franchise's worst since a .409 mark in 1994. -- David Schoenfield (@dschoenfield), SweetSpot

In a week highlighted by the debut of Matt Duffy at shortstop and Brad Miller continuing to mash, the pitching staff allowed six or more runs in four of six games this week (Monday through Sunday).

Brian Dozier homered in all three games against the Royals at Target Field over the weekend.
