THURSDAY: The Mariners have announced the signings of Wolf and Miner.

Wolf will earn $1MM if he makes the roster, reports Ken Rosenthal of FOX Sports (links all to Twitter). The contract also includes a variety of incentives tied to appearances (as a reliever or starter), days on the roster, and innings pitched. If Wolf maxes out his deal, says Rosenthal, he could reach $4.25MM in earnings.

TUESDAY, 1:05pm: Miner will earn $750K if he makes the Major League team and has a June 15 opt-out date, tweets Chris Cotillo of MLB Daily Dish.

10:54am: The Mariners have agreed to a minor league deal with an invitation to Spring Training with veteran lefty Randy Wolf, tweets Ryan Divish of the Seattle Times. Divish also tweets that the Mariners will sign right-hander Zach Miner to a minor league deal with an invite to Spring Training. Wolf is a client of the Wasserman Media Group, and Miner is represented by the Boras Corporation.

Seattle views Wolf as a potential bullpen option, tweets Jon Heyman of CBS Sports. The 37-year-old missed the entire 2013 season after undergoing Tommy John surgery late in the 2012 campaign. In that 2012 season, Wolf struggled to a 5.65 ERA with 5.9 K/9, 3.0 BB/9 and a 42.9 percent ground-ball rate (the highest of his career). Despite those struggles, he was solid for the Brewers the prior year, posting a 3.69 ERA in 212 1/3 innings out of their rotation.

Wolf owns a 4.20 ERA in 2268 career innings at the big league level and is a veteran of 14 Major League seasons with the Phillies, Astros, Dodgers, Brewers, Padres and Orioles.

Miner, 32 in March, pitched 28 1/3 innings for the Phillies in 2013 — his first Major League action since 2009. Miner turned in a 4.40 ERA with nearly as many walks (17) as strikeouts (20) in that time. However, there were a good deal of positives in Miner's game as well; his velocity was up more than a full mile per hour (91.8 mph average in 2013 compared to 90.7 in 2009), and he posted a strong 48.9 percent ground-ball rate.

Miner has a 4.25 career ERA in 385 1/3 innings between the Tigers and Phillies. Presumably, Seattle likes him as a potential swingman — a role he's had throughout the entirety of his Major League career to this point. Miner has appeared in 173 big league games, including 38 starts.
