From the article:

"I don't have a problem with weightlifting," Watkins went on, "it's lifting heavy weights over their heads that I have a problem with."

Sound familiar to you? Hmmm....

"Basically, the overhead press (like most overhead lifts) are contraindicated in the overhand throwing motion. This means that any lift where the elbows go above parallel with the shoulder blades should be avoided and something should be substituted for them. The Pendlay Row is a perfect exercise to build scapular strength for throwers of all kinds, so it's a natural substitution!"

I would like to stress that I think the Press is a fine exercise during the offseason for baseball pitchers. but should absolutely be avoided in-season for the reasons I've already pointed out.
