CHICAGO -- The Cubs have acquired Cole Hamels from the Rangers to bolster their rotation.

The Cubs are sending Texas Class A right-handed pitcher Rollie Lacy, right-hander Eddie Butler and a player to be named later. Texas is also sending cash to the Cubs with MLB.com's T.R. Sullivan reporting the Rangers are picking up a significant portion of the $14 million left on Hamels' contract.

Hamels bolsters a rotation that has not performed up to sky-high preseason expectations. Prize offseason acquisition Yu Darvish has made eight starts all year, and Tyler Chatwood has struggled to throw strikes. Even if Hamels does not pitch to the levels he reached earlier in his career, he should offer a steady hand to a starting five that could use the help. Darvish and Hamels were teammates on the Rangers from 2015-17, and Darvish posted a picture of him and Hamels on Instagram with the caption: "I can't wait to see you Cole!" Hamels responded in the comments, "Look forward to it too buddy!!"

Asked about Hamels after Thursday's game, Cubs manager Joe Maddon joked that his teams have had trouble with the left-hander in the past. Maddon would know. Hamels was the World Series MVP in 2008 against Maddon's Rays in the Phillies' five-game Fall Classic triumph.

"He'd be pretty good," Maddon said. "I've not liked him for a long time. He's pitched some really big games against teams that I've been involved with and has done really well. He's a great competitor. He's got good stuff, but he competes and he knows what he's doing out there. I'd have to rank him as a pretty competent Major League left-handed pitcher."

Hamels apparently does like pitching at Wrigley Field, throwing a no-hitter there on July 25, 2015, in his final start for the Phillies before he was traded to the Rangers. It was the first time the Cubs were no-hit since the Dodgers' Sandy Koufax did so on Sept. 9, 1965, a stretch of 7,920 games. Hamels is 3-1 with a 1.76 ERA in six career starts at Wrigley Field.

This season, Hamels is 5-9 with a 4.72 ERA in 20 starts. Hamels was 1-7 with a 6.41 ERA in 10 starts at Globe Life Park in Arlington, serving up 16 home runs, but has fared much better on the road, posting a 4-2 record and 2.93 ERA in 10 starts.

"All through his career he has been on winning teams," Rangers shortstop Elvis Andrus said. "When something happens, it's tough to adjust. It's not like he needs a lot of things to fix. He needs to be in competition and competing. He's going to a good team. He'll be fine. As soon as he walks out there, he'll be a different animal."

Hamels is making $23.5 million this season with a club option of $20 million with a $6 million buyout.

"He threw the no-hitter here, but when I was with the Rays, he was a pain in the butt, when he was with the Phillies and with the Rangers," Maddon said. "It always seemed to not work out well [for us]."

This spring, Maddon talked about how they had the best rotation since he arrived in Chicago in 2015. However, the starters, with the exception of All-Star Jonathan Lester , haven't lived up to the hype as Darvish has been limited because of injuries and Chatwood, Kyle Hendricks and Jose Quintana haven't been consistent.

Darvish was to throw off a mound on Friday for just the second time since June 29. There's no timetable for his return.

Chatwood, who signed a three-year contract last December, has been a puzzlement. He continued to struggle with his command, and now leads the Majors with 85 walks over 94 innings. Asked before the game if the Cubs have enough talent on the current roster if they don't make a move, Maddon brought up the right-hander's name.

"We would have to have Chatwood pitching as well as he possibly can," Maddon said. "Darvish in the wings is the really intriguing part. I don't know when that will occur, but that's about as good of an acquisition as we can get right now."

Anthony Rizzo , who hit a walk-off home run in Thursday's 7-6 win over the D-backs, backed the current Cubs rotation.

"I think the best is yet to come for our starting rotation," Rizzo said. "I like our guys and I like our chances every single time a guy goes out."
