The Pittsburgh Pirates have had an excellent week, going 4-2 in their six games played. Any disappointment leftover after splitting a very-winnable series against the San Diego Padres was quickly swept away after the Bucs took all three games against the defending champion San Francisco Giants. The sweep has put the team in a great position for a very successful road trip as they open a three game series in Atlanta tonight.

So who was the player most responsible for the previous week’s success in Pittsburgh Pirates baseball?

Starting this week, we will take Friday mornings to completely rank the entire 25-man Pirates roster and try to find that answer. Let’s get started with #25-#21

25 Corey Hart #12 Last week: n/a

Last rank: n/a If we didn’t make a pledge to rank EVERY player on the Pirates 25-man, Corey Hart may not even make it into this piece. He is now completely marginalized and has no clear role on the club. Going 0-for-2 in a full week of games and not making a start since May 16 will slap that label on you.

24 Antonio Bastardo #59 Last week: n/a

Last rank: n/a Antonio Bastardo earns a spot in this week’s rankings simply because we didn’t notice him this week, which is a good thing. Bastardo pitched a grand total of one inning over the past week, striking out one without completely imploding. It seems silly to think that such a brief blip could serve as “something to build on” but in Bastardo’s case, it can’t hurt. earns a spot in this week’s rankings simply because we didn’t notice him this week, which is a good thing.

23 Jeff Locke #49 Last week: n/a

Last rank: n/a Jeff Locke is a left-handed pitcher for the Pittsburgh Pirates. Jeff Locke is struggling mightily this year. Therefore, Jeff Locke deserves this low ranking. In the annals of Bad Locke Starts, his start against the Padres earns a special mention. 4.0 IP/8 H/7 R (six earned) indicates a complete lack of control over the game from the very first pitch he threw. Locke is very much in danger of losing the fifth spot in the Pirates rotation. is a left-handed pitcher for the Pittsburgh Pirates.is struggling mightily this year.

22 Rob Scahill #52 Last week: n/a

Last rank: n/a Prior to serving up a walk-off grand slam to Derek Norris of the San Diego Padres, Rob Scahill had shown to be a serviceable if-not spectacular bullpen arm, giving up runs here and there, often meaningless, and often throwing multiple innings. In his next appearance since the walkoff, in Wednesday’s sweep-clinching win over the Giants, Scahill entered the ninth with a 5-1 lead, seemingly a low-pressure situation. Scahill could only get one batter out, giving up three hits and a run, to force Clint Hurdle‘s hand to bring in Mark Melancon for an unexpected save.

21 Sean Rodriguez #3 Last week: n/a

Last rank: n/a Sean Rodriguez is now known as Pedro Alvarez‘s personal caddie, and perhaps rightfully so. Over the past week, Rodriguez did not get a start and often did not get an at-bat when he did come in, going a total of 1-3 over the past week. Not much to say here. It has become perfectly clear that the Pirates prefer to keep Pedro Alvarez‘s offense in the lineup as much as possible. We must mention that Rodriguez has been rock-solid defensively and has yet to commit an error in 2015. is now known as‘s personal caddie, and perhaps rightfully so.

We continue with the next five Buccos on the next slide.
