--DH Victor Martinez tore his left anterior cruciate ligament during offseason training, and he could need season-ending surgery.
An MRI exam Jan. 16 in Lakeland, Fla., the Tigers' spring training home, revealed the injury.
The team said Martinez would be re-evaluated during the week of Jan. 23-29, but surgery likely would cost him the entire 2012 season.
In his first season with the Tigers, the switch-hitting Martinez batted .330 with 103 RBI last season in helping Detroit win the AL Central.
--3B Nick Castellanos is one of 18 non-roster invitees to spring training by the Tigers and despite not turning 20 until March 4, he will get valuable experience working with veterans. Castellanos competed at the low Class A level last year and wound up hitting more than .300 after a weak first month. He has no chance to make the team this year, but the Tiger hope he can compete at some point in 2013.
--LHP Drew Smyly, a second-round draft choice in 2010, was one of 18 non-roster invitees to Detroit's Spring Training. Smyly hopes to work in the path of LHP Adam Wilk, who preceded Smyly as the organization's minor league Pitcher of the Year and wound up pitching briefly for the Tigers last season. Smyly compiled a 1.18 ERA in eight games at Double-A Erie after a solid season for high Class A Lakeland.
--RHP Rick Porcello is in line for a hefty raise after turning down his contract option for this season. Porcello declined his $1.344 million option after learning he was eligible for arbitration a year early as a "Super Two" player. The 14-game winner will get more than $3 million his new one-year deal. Detroit also settled with all of its other arbitration eligible players, including Delmon Young and Max Scherzer. The Tigers have settled all of their arbitration cases without completing the process since Dave Dombrowski took over running the club in 2002.
--LHP Casey Crosby, added to Detroit's 40-man roster this winter, bounced back from a season of elbow-enforced idleness to pitch a complete season last year. Crosby showed his good fastball plus solid curve and changeup but was wild, possibly the effect of missing two complete seasons. The organization has kept him in a starting role to speed his development, but with a surplus of southpaws he might at some point work out of the bullpen. He is regarded as one of Detroit's top pitching prospects.
--SS Jhonny Peralta begins his second season as Detroit's starting shortstop. Peralta turned in exactly what the Tigers expected defensively, maybe not the greatest range in the world but extremely reliable, while exceeding expectations offensively. Peralta batted .299 with 21 home runs and 86 RBI. Manager Jim Leyland praised his steadiness all season. Peralta played 146 games last season, about what he would figure to play in 2012.
BY THE NUMBERS: 0 -- Members of Detroit's World Series winning 1984 team in baseball's Hall of Fame. RHP Jack Morris is the closest after having received two-thirds of the ballots cast for the 2012 class. Morris finished second in the balloting but fell short of the three-fourths needed to enter the Hall of Fame. He has two of his 15 election chances left.
QUOTE TO NOTE: "I'm not going to plead my case. I am grateful, though, that more voters think of me as a Hall of Famer. I must have had a good year." -- RHP Jack Morris, after the leading pitcher on the 1984 World Series winning Tigers received two-thirds of the votes cast but fell short of the three-fourths necessary for membership in baseball's Hall of Fame.
