Nicholas Castellanos has evidently found a ballpark that suits him.
Castellanos — who openly complained about Comerica Park's spacious dimensions earlier this year when he was with Detroit — has flourished since a trade to the Chicago Cubs. The 27-year-old outfielder has hit 13 home runs for Chicago in 35 games. That's two more than he hit in 100 games this season for the Tigers.
Castellanos has hit six home runs at Wrigley Field after hitting only three at Comerica this year.
Castellanos could be crucial for the Cubs down the stretch. They dropped the final three games of a series against Milwaukee and lead the Brewers by just two games for the second wild card in the National League. Philadelphia is also two back, and surging Arizona is 1½ behind after winning 11 of 13.
Chicago has injury problems. Shortstop Javier Báez is dealing with left thumb issues, and closer Craig Kimbrel has had elbow inflammation. If the Cubs do make the postseason, they can thank Castellanos.
Not every big trade at the deadline has paid dividends. Marcus Stroman has a 5.05 ERA in seven starts for the New York Mets. Yasiel Puig has only two home runs in 33 games for Cleveland. Zack Greinke is 4-1 for Houston, but he's posted a 3.86 ERA since being traded to the Astros and hasn't really been dominant.
Castellanos is the acquisition who has really made a difference. He's hit .338 for the Cubs with an OPS of 1.056.
In another interesting twist from those deadline deals, the Diamondbacks traded Greinke and still might make the playoffs. Alex Young struck out 12 on Saturday for a team rookie record, allowing two hits in eight innings in a 2-0 win over Cincinnati. Young is 7-3 with a 3.38 ERA on the season.
