Andy Pettitte is returning to the New York Yankees after more than a year in retirement, and will start Sunday against the Seattle Mariners, Yankees general manager Brian Cashman told reporters.
Since the announcement of his return, the lefty has been touring the organization's minor-league affiliates to build up arm strength and refine his pitches.
In his final minor-league outing, an outing for Triple-A, the veteran allowed five runs and eight hits in five innings. In four outings, he posted a 3.71 ERA in 17 innings.
"Everybody's in agreement he's not going to benefit from any more time below," Cashman said. "I think the fans are excited. I know Andy's really excited."
Pettitte, who will turn 40 next month, signed a $2.5 million deal in March. He last pitched in the majors on Oct. 18, 2010, tossing seven innings in a Game 3 loss to the Texas Rangers in the ALCS.
---The progress of the Milwaukee Brewers has led to contract extensions for general manager Doug Melvin and manager Ron Roenicke, the team announced Tuesday.
Melvin, whose extension runs through the 2015 season, also received a promotion to President of Baseball Operations, General Manager. Roenicke's contract will run a year shorter, through 2014 with a club option for 2015.
Melvin arrived on Sept. 26, 2002. Before that, he was GM of the Texas Rangers from 1996-2001.
Roenicke was named manager on November 4, 2010. In his first full season as a major-league manager, he led the Brewers to a franchise-record 96 wins and their first division title since 1982.
---Washington Nationals third baseman Ryan Zimmerman has returned to the active roster.
As expected, the team activated their injured star from the 15-day disabled list. He replaced injured right fielder Jayson Werth on the team.
Zimmerman, 27, is batting .224 with one home run. His absence initially paved the way for the arrival of top prospect Bryce Harper.
---Mariano Rivera's knee evaluation didn't go so well, his agent told the New York Daily News.
"We ran into complications," agent Fernando Cuza told the paper. "I am referring to [Yankees team] Dr. [Christopher] Ahmad and [Yankees general manager] Brian Cashman for further information."
On Tuesday, an unnamed Yankees official told ESPNNewYork.com that he didn't believe the complications were serious, but said the team was still gathering information. Another source told ESPN the Magazine's Buster Olney the complications won't have any bearing on Rivera's ability to have surgery and return from the injury.
---The Cleveland Indians optioned pitcher Zach McAllister to Triple-A Columbus on Tuesday.
The righty pitched the first game of Monday's doubleheader against the Chicago White Sox and earned his first major-league win by allowing four runs in six innings. His departure returns the roster to 25 players.
---The Softbank Hawks of the Japanese Pacific League team released former major league pitcher Brad Penny after one start, the Hawks announced Tuesday.
Penny requested his release. He reportedly was having difficulty adjusting to life in Japan, according to the Asahi Shimbun, a newspaper in Japan. He also had reportedly suffered a shoulder injury after making his only start and had missed the past month.
He has offers to pitch as a starter and a reliever in the major leagues and expects to decide on a destination soon, a baseball source told ESPN The Magazine's Buster Olney.
---The Milwaukee Brewers have signed infielder Tommy Manzella to a minor league contract, according to FOXSports.com's Ken Rosenthal.
Manzella will provide depth at shortstop after Alex Gonzalez (knee) went down for the season. The 29-year-old batted .225 with a .531 OPS in 83 games with the Astros in 2010.
---The Chicago White Sox optioned Jose Quintana to Double-A Birmingham, after he worked 5 2/3 shutout innings Monday in his major league debut.
Quintana, 23, pitched first game of a doubleheader against the Cleveland Indians. He was up as the 26th man, allowed by MLB this season for double-headers.
---The Baltimore Orioles have summoned Zach Phillips from Triple-A Norfolk.
The team hasn't announced a corresponding roster move, but the 25-year-old Phillips has a 4.15 ERA and 11 strikeouts in 13 innings at Triple-A.
---The Kansas City Royals recalled Vin Mazzaro from Triple-A Omaha.
The right-hander had a 4.37 ERA and 27 strikeouts in 35 innings in six starts. He takes the place of Tommy Hottovy, who was sent down after working 5 1/3 innings during his two-week stay with the team.
