The Mariners are a tough team to figure. To begin with, they’re the only team in the major leagues with a winning record that has been outscored by its opponents. They’re also run extremely hot and cold over the past three weeks, first losing six straight to the Twins and Angels, then taking seven of eight from the Rangers, A’s, Royals, and White Sox. The M’s also had five of their first twenty games postponed by snow or rain, though they’ve already made one of those up, falling to the Red Sox in Boston last night on Manny Ramirez’s game-winning shot off Chris Reitsma in the eighth.

Thus far, the only thing that’s really working for them on offense is catcher Kenji Johnjima (.305/.349/.508). That’s not much of a surprise given that their big offseason acquisitions were Joses Vidro and Guillen. More surprising: Richie Sexson is really struggling (.150/.253/.375) and after finishing fifth in the AL in stolen bases last year, the M’s are dead last in the majors having gone just 6 for 10 on the bases thus far in 2007. On the other side of the ball, Felix Hernandez looked to be breaking out only to go down with a scary elbow injury. He’s expected back next week, but M’s fans will likely continue to hold their breath over the health of King Felix for a while longer. Behind Hernandez’s scary elbow has been more scary pitching in the form of starters Miguel Bautista (6.30 ERA), Horacio Ramirez (6.64) and old buddy Jeff Weaver (0-4, 18.26 in four starts). If not for the unlikely performance of Jarrod Washburn (2.88 ERA, 0.99 WHIP) and the solid showing by their bullpen (3.35 ERA) the M’s would be in a much worse way, which, frankly, I assume they will be before to long.

Tonight, the Yanks draw South Korean-born Cha Seung Baek, who’s holding King Felix’s spot in the rotation. Baek has started against the two worst teams in the American League and produced one solid start, that coming against the Royals at Safeco. The Yankees last tussled with Baek in Jeff Karstens’ major league debut last August. Baek and Karstens matched one another roughly pitch-for-pitch in that contest, with Bobby Abreu homering of Baek and the Yankees pulling ahead against the Mariner bullpen only to see Jaret Wright and Ron Villone blow the game in the final two frames. Tonight, Baek’s mound opponent will be Kei Igawa, who salvaged his spot in the Yankee rotation with a fantastic emergency appearance last Saturday after Karstens had his leg broken by a comebacker on the first pitch of the game. Afterwards, Joe Torre speculated that Igawa might have been well served by the lack of warning, which prevented him from overthinking his outing, or building up nerves. It will be interesting to see how he does tonight, having had the last week to think about tonight’s start.

Incidentally, Igawa still leads the Yankees in wins, though he’s now tied with Luis Vizcaino, who vultured Andy Pettitte’s second win in game one yesterday. His five outings can be split into two awful ones:

9 1/3 IP, 16 H, 14 R, 4 HR, 6 BB, 5 K (13.50 ERA, 2.36 WHIP)

And three solid ones:

17 1/3 IP, 10 H, 5 R (4 ER), 1 HR, 7 BB, 14 K (2.08 ERA, 0.98 WHIP)

If the Yankees can find a way to keep Igawa on his game, they could have one of the best fourth starters in baseball.
