Montas lasts less than two innings in ugly start for A's

Frankie Montas was back on the mound for the A's against the Arizona Diamondbacks on Tuesday, but the starter wasn’t better than ever.

In 1 2/3 innings pitched, Montas allowed six hits, nine earned runs and two homers to balloon his ERA to 4.74 before the A’s turned to the bullpen.

Arizona didn't take long to start scoring. Kole Calhoun scored on a wild pitch before the A's even recorded an out in the bottom of the first, then the wheels kept turning.

Balls normally fly at Chase Field, but the ones hit off of Montas on Tuesday were extra spicy. Nick Ahmed's home run in the bottom of the second had a 106 mph exit velocity.

This was way out of character for Montas, who, heading into Tuesday’s outing, had allowed just four total runs all season. He also had never given up more than seven runs in an outing during any of his five MLB seasons.

Montas had missed his original start against the Giants on Friday due to upper back tightness, but still wasn’t ready to go on Saturday … or even Sunday. Despite Montas feeling better, A’s manager Bob Melvin figured Tuesday would be a better start date for Montas.

It's not clear if the upper back tightness continues to be an issue, but we should know more later on.
