Padres waiting to make decision on Grandal

PHOENIX -- Don't be surprised to see catcher Yasmani Grandal join the team on Tuesday in Seattle when he completes his suspension for violating Major League Baseball's Joint Drug Prevention and Treatment Program.

Last November, Grandal was suspended for the first 50 games of the 2013 season after testing positive for testosterone. He's been playing with Triple-A Tucson since May 18.

"We're going to see what happens this weekend and see what happens [Sunday], and then get together to make a decision," Padres manager Bud Black said. "Nothing is imminent and nothing is etched in stone, but it's a high probability."

Grandal went 3-for-5 Saturday against Sacramento and is hitting .313 with three doubles and two RBIs in his first eight games at Triple-A. He has also struck out 10 times in his first 32 at-bats.

Acquired as part of the trade with Cincinnati for Mat Latos, Grandal hit .297 with eight home runs and 36 RBIs in 60 games after being called up last season on June 1.

It's unclear if Grandal would have been ready for the season if he had not been suspended because of the two inflamed tendons on his left side that have plagued him since the end of last season.

Gyorko using aggressiveness to limit strikeouts

PHOENIX -- Jedd Gyorko has already tied the Padres' rookie record with five home runs in May and needs one more home run to tie the club's rookie record for home runs hit in any month.

But it's the second baseman's strikeouts, or his lack thereof, that are also gaining attention.

Gyorko struck out 266 times in 1,502 plate appearances in three Minor League seasons. He has struck out 39 times in 189 plate appearance in the big leagues entering Sunday's series finale against the D-backs.

"I'm just trying to put the ball in play and battle with two strikes," Gyorko said. "The best way not to strike out is to not to get to two strikes, so I try to be aggressive early in the count. Hopefully, I can get my pitch and try to put a barrel on it."

That said, if Gyorko's next home run comes this month, it will put him in an interesting company of players.

Benito Santiago (1987), Will Venable (2009) and Nate Colbert (1969) all hit six home runs in one month as a rookie. Melvin Nieves hit five home runs in May as a rookie in 1995.

"I consider myself a gap-to-gap hitter, and if I get a hold of one, I have enough power to get it out," Gyorko said. "It comes back to getting back to a basic approach. In April, I wasn't hitting the ball with much authority, and this month I've been able to get my timing together."

Worth noting

• The club is expected to make a roster move to make room for Monday's starter, Clayton Richards (intestinal virus). He has been on the disabled list since May 5.

• Cameron Maybin (wrist) went 2-for-5 in the second game of his rehab assignment with Triple-A Tucson. He's had five at-bats in two rehab games, and the club has said it would like him to get at least 30 at-bats before they consider activating him from the disabled list. He's been sidelined since April 17.
