Quick Hits: Matsuzaka, Kroon, Maine, Mariners

On this date in 1975, Nolan Ryan won his 100th career game in style, pitching his fourth no-hitter and tying Sandy Koufax's record (a mark Ryan would later eclipse). Here are the latest links from around the Major Leagues…

• Daisuke Matsuzaka is leaning toward Tommy John surgery, according to Yahoo's Tim Brown (Twitter link). Dr. Lewis Yocum found a significant tear in Matsuzaka's elbow and the right-hander will now discuss his options with the Red Sox.
• In honor of the many intriguing draft-eligible college pitchers, Jerry Crasnick of ESPN.com reviews nine current MLB pitchers who didn't spend much time in the minor leagues. 
• Marc Kroon, who was a candidate to make the Giants' Opening Day roster, has decided not to opt out of his Triple-A contract, according to Andrew Baggarly of the San Jose Mercury News. The 38-year-old has not appeared in the Majors since 2004, but he has a 3.10 ERA with 11.1 K/9 and 4.4 BB/9 in 20 1/3 innings at Triple-A this year. It would be great to see the 1991 second rounder get another chance in the big leagues.
• Similarly, John Maine is staying in Triple-A instead of exercising his opt-out with the Rockies, according to Troy Renck of the Denver Post (on Twitter).
• Geoff Baker of the Seattle Times says it's time for the Mariners to make a move and find some "players who can square up on a ball more than a couple of times per week."
