With the tournament being held in March, a lot of MLB front offices are wary of letting their guys compete. They're fearful that their players could get hurt and miss the season.Fernando Reyes@Fernanviews@Shawn_Spradling Unbelievable@Shawn_Spradling UnbelievableD.J.

Thanks @mlb @Mariners twitter.com/shawn_spradlin…Fans are calling for the league to do the same thing for Team USA, but they have. Team USA is rolling out Kyle Freeland as one of the pitchers in its starting rotation. If the MLB teams had no say, Team USA's starting rotation would be Justin Verlander, Max Scherzer and Gerrit Cole.It's difficult to get all the stars in baseball to commit to the event. The World Baseball Classic is so close to spring training, but that's the only time they can hold the tournament.The Seattle Mariners don't want Luis Castillo to get injured playing in the World Baseball ClassicSeattle Mariners pitcher Luis CastilloAcquiring Castillo from the Cincinnati Reds at the trade deadline last season was huge for Seattle. It added another ace-type pitcher to its rotation. He immediately made an impact on the team.Luis Castillo shut down the Toronto Blue Jays in the postseason. He went 7.1 innings, giving up zero runs and striking out five along the way.Seattle is looking for more of the same from Castillo this season. If so, the Mariners could be very competitive in 2023.
