Jered Weaver losing velocity as career-high workload piles up

5 Comments

Jered Weaver got himself back on track following a shaky stretch in which his ERA rose from 1.78 to 2.49 in five starts, tossing eight innings of one-run ball against the Yankees on September 9 and seven innings of one-run ball versus the A’s on Wednesday.

However, with Weaver just three innings away from tying his career-high workload Mark Saxon of ESPN Los Angeles notes that the right-hander’s velocity is down compared to early in the season.

Here are Weaver’s average fastball velocities by month from Fan Graphs:

April: 90.3 mph
May: 89.7 mph
June: 88.7 mph
July: 89.1 mph
August: 88.7 mph
September: 87.9 mph

Weaver has never been the type of pitcher to blow away hitters with fastball velocity, but he certainly seems to be wearing down somewhat. Not coincidentally his ERA has jumped from 1.86 in the first half to 3.33 in the second half and his strikeout-to-walk ratio has declined from 3.8 to 2.8.

And with the possibility of Weaver starting on short rest Sunday the Angels have to wonder how much he’ll have left in the tank if they somehow make the playoffs.
