Maybin returning to Padres today
By Corey Brock / MLB.com
LOS ANGELES -- Padres center fielder Cameron Maybin, who has missed the last 45 games due to a right wrist impingement, was reinstated from the disabled list on Thursday.
Maybin will be in uniform in Denver, where the team begins a four-game series.
Yonder Alonso was placed on the 15-day disabled list, retroactive to Saturday.
Maybin played in nine games during his Minor League rehabilitation stint with Tucson, hitting .323 in 31 at-bats with three home runs, four RBIs and an .447 on-base percentage. He played his last game with Tucson on Tuesday, going 3-for-6 with a home run.
Maybin sustained the injury making a difficult catch at Dodger Stadium in April. He considered having surgery but opted against it. Maybin could revisit the idea following the season. That same wrist has troubled him in each of his first two seasons with the Padres.
Maybin is hitting .091 in 33 at-bats with six strikeouts. In his absence, the Padres have used Will Venable, Alexi Amarista and Chris Denorfia in center.
Slumping Headley seeks more patience at the plate
LOS ANGELES -- So what's wrong with Chase Headley?
Headley was hitless in five at-bats in Tuesday's 9-7 loss to the Dodgers, dropping his average to .229. The Padres' third baseman had one hit in his last 25 at-bats entering Wednesday night's series finale with the Dodgers and was hitting .139 in 72 at-bats since May 17.
"It's a combination of things. First and foremost, I've got to swing at better pitches," Headley said. "I'm getting myself out. I'm making him [opposing pitcher] thrown one quality strike. And there has been a little bad luck mixed in there, too."
Headley is seeing fewer pitches per plate appearance (3.90) than any other time during his career and fewer than he saw a year ago (4.04). His swing-and-miss percentage (29.9) is also up from 2012 (26.6), when he led the league with 115 RBIs.
"When things happen like this, it's not usually just one thing," Headley said.
San Diego manager Bud Black said Headley isn't tracking the ball as well as he has in the past and went as far to call Headley's slump "uncharacteristic."
"I think more than anything, he's probably a little overaggressive early in the count," Black said. "The uncharacteristic early-count swings on pitches out of the zone. He knows it. And for Chase, I think it's frustrating because he knows that's not his game. Right now, he's swinging at pitches out of the zone."
According to Baseball Solutions, Headley's contact rate has dropped from 74 percent a year ago to 71.6 percent this season.
Lake Elsinore's Asencio among May award winners
LOS ANGELES -- The Padres on Wednesday announced their Minor League players of the month for May, as selected by the player development staff.
Class A Lake Elsinore outfielder Yeison Asencio was named Hitter of the Month after batting .320 in 28 games for the Storm in May. He had 11 extra-base hits and 25 RBIs to go with a .400 slugging percentage. Asencio also played errorless defense in right field. For the season, he's hitting .292 with 45 RBIs, the most in the organization.
Double-A San Antonio reliever Kevin Quackenbush was named Pitcher of the Month after not allowing an earned run over 14 games and 13 1/3 innings. He was 1-0 with seven saves in eight opportunities while allowing one unearned run. He has 10 saves in 11 opportunities and a a 0.35 ERA for the Missions.
Lake Elsinore outfielder Travis Jankowski was named Baserunner of the Month after stealing 18 bases in 19 attempts. He currently leads the organization with 36 steals in 39 attempts and is hitting .270.
Class A Fort Wayne outfielder Alberth Martinez was selected as Defensive Player of the Month after making one error in 27 games with 63 putouts and five assists in 69 total chances. He has a .975 fielding percentage. He has three errors in 122 totals chances with 112 putouts and seven assists on the season.
Also Wednesday, five members of the Fort Wayne TinCaps were named to the Midwest League All-Star game -- designated hitter Jeremy Baltz, catcher Dane Phillips, pitchers Roman Madrid, Joe Ross and first baseman Luis Tejada.
• Padres first baseman Yonder Alonso (right hand contusion) missed his fourth consecutive game on Tuesday and wasn't in the starting lineup on Wednesday, a day after he tested his hand by hitting in the cage and later during batting practice.
As it turns out, he might have hit too much. His hand was still sore on Wednesday.
"I think the volume [of hitting] might have caught up to him," said Black, who called a disabled list stint "highly unlikely."
