The Colorado Rockies have signed Rafael Betancourt to a Minor League contract.

The right-hander will report to extended Spring Training with the Rockies.

Betancourt, who turns 39 next week, is attempting a comeback from Tommy John surgery.

The five-year deal Sean Doolittle reached with the Oakland Athletics over the weekend is worth $10.5 million.

The contract will increase to $13.75 million if he becomes eligible for salary arbitration after this season.

Doolittle began the 2014 season with 1 year, 122 days of Major League service. The cutoff for arbitration eligibility was exactly 2 years, 122 days last winter, and for the 2012-13 offseason, it was 2 years 139 days.

The left-hander has a 3.38 ERA, 0.84 WHIP and 11 strikeouts in 10.2 innings this season.

The A's are rewarding Sean Doolittle, giving the left-hander a five-year contract Friday.  The deal contains a pair of club options that could extend the agreement through the 2020 season, according to an ESPN.com report.

The San Diego Padres have signed Jedd Gyorko to a six-year, $35 million contract extension, according to a source.

The agreement includes a $13 million option for 2020, which would be a seventh season.

Gyorko hit .249 with 23 home runs and 63 RBIs in 125 games last year, leading all Major League rookies in home runs and ranking second in RBIs, third in doubles (26) and fifth in hits (121).

The Cardinals extended the contract of GM John Mozeliak for two years through the 2018 season, according to an ESPN.com report on Saturday.

Mozeliak has been with the Cardinals organization for the last 19 seasons, the last six as GM. During Mozeliak's tenure, the Cardinals have been to the postseason four times, winning two NL pennants, and a World Series in 2011.

The Arizona Diamondbacks are expected to sign Randy Wolf to a Minor League contract, according to a source.

Wolf signed a Minor League deal with the Seattle Mariners this past February, but he requested and was granted his release by the club after disagreeing with a "45-day consent release" Seattle asked him to sign.

The 37-year-old didn't pitch in the Major Leagues last year because of Tommy John surgery, but he's 132-117 with a 4.20 ERA in 376 appearances (368 starts) over parts of 14 seasons.

The Chicago White Sox have reached an agreement on a Minor League deal with Tommy Hanson.

The Atlanta Braves traded him to the Los Angeles Angels in exchange for setup man Jordan Walden last offseason, but he found himself non-tendered this winter.

He signed a split contract with the Texas Rangers earlier this offseason but failed to make the club after yielding 10 runs in 14 Spring Training innings.

The Boston Red Sox have signed Ryan Roberts, while optioning Brock Holt to Triple-A Pawtucket.

Roberts gives the Red Sox insurance at third base with Will Middlebrooks on the disabled list with a calf strain.

The 33-year-old was cut by the Chicago Cubs this spring. He has spent parts of the past eight seasons in the majors.

The Pirates have signed GM Neal Huntington and manager Clint Hurdle through the 2017 season, with a club option for 2018.

Pittsburgh won 94 games in 2013 and advanced to the playoffs for the first time since 1992, and Hurdle was honored as the manager of the year in the National League.
