The Chicago Cubs have called up righty Marcos Mateo from AAA Iowa to join the rotating cavalcade of bullpen arms. Mateo, 26, had an outside shot of making the Cubs’ pen out of Spring Training, but instead settled for AA. He pitched well, and made his way up to AAA, where’s he’s been just so-so. He leaves behind a 4.97 ERA (bad) and a 1.263 WHIP (not that bad), and 15 strikeouts in just over 12 innings.

As for Mitch Atkins, he had an ugly 7.20 ERA and 1.900 WHIP over a few bullpen appearances. He’ll head back to Iowa and likely return in September when rosters expand.
