And true, it was only batting practice.
But D-backs non-roster outfielder Wily Mo Pena still put on quite a show during batting practice Saturday at Salt River Fields.
"First round, 10 swings, nine homers," second baseman Kelly Johnson said. "If there were 30 swings, I'm guessing 25 over the fence. It was ridiculous."
Pena's batting-practice power has always drawn attention during his time with the Reds, Red Sox and Nationals. The D-backs signed the 29-year-old to a Minor League deal this offseason with the idea that he would provide some outfield depth at Triple-A Reno.
At 6-foot-3 and around 280 pounds, Pena drew looks from teammates before even stepping on the field.
"It's the first time I've been in a [hitting] group with him," Johnson said. "Everybody has heard about him. Since my first year in pro ball that's one guy everyone talks about, his home runs in BP."
