Knapp has already been placed on the disabled list and is likely to miss the remainder of August.
This means more MLB exposure for catching prospect Jorge Alfaro.
However, when asked Wednesday about the noticeable dip in his velocity from spring training through his first two, and likely only, starts for the Phillies, Buchholz conceded he hadn't been completely healthy."I wasn't 100 percent, but I wasn't 40 [percent].
I was probably throwing at 85 percent, just trying to do what I was doing, get by and build arm strength," Buchholz said.
His fastball sat at 90.1 mph with his hardest topping out at 92.3 mph during his two outings. That was the best I've felt in a game warming up before my last start.
Herrera hasn't played since suffering a strained hamstring on Monday and the club couldn't afford to go another day with a short-handed bench.
Herrera shouldn't need more than a minimum stint on the disabled list. Altherr obviously returned from the DL too soon, so the Phillies will exercise a bit more caution this time around.
That was a drop of 1.2 mph and 2.6 mph, respectively, from what he posted in 2016 with the Red Sox. It just sort of jumped up and got me."Me at 40 percent throwing is not near good enough to play at this level," he added.
Still, nothing made Buchholz believe he was on the precipice of a suffering a season-ending injury. Buchholz, who is earning .5 million this season, felt bad about getting hurt so quickly into his Phillies' tenure, leading him to apologize to general manager Matt Klentak during a phone call as well as to his teammates. And if the 32 year old gets his way, he'll overcome the long-shot odds and be back on the mound in a Phillies uniform in September."I wanted to be good," Buchholz said.
