Crappy news for the A’s, who are off to a good start, but great news for both Cahill and Mazzaro, who will get to join the A’s rotation for the foreseeable future. Cahill sure didn’t look good in his first start Friday, but he won 10 games as a rookie with the A’s last season and in his two starts at Triple-A before his recall, he sparkled. While Duchscherer hasn’t officially been put on the DL, considering his history with hip injuries, it’s most likely a matter of when not if. And when that happens, Mazzaro is the most likely candidate to take his starts. Mazzaro was hit hard in the bigs last year, but he’s been a superb Triple-A pitcher the past couple of seasons, and is averaging better than a K per inning with a 2.59 ERA through four starts and one relief appearance at Sacramento. Both Cahill and Mazzaro are worth gambling on in AL-only leagues, but you’re probably best off cherry picking when to start them until they get into a rhythm.
