It's Sept. 25 and David Ortiz is about to play his 135th game of the season including his second consecutive game at first base.

As Red Sox surprises go that tops the list.

Considering Ortiz missed the final two months of last season and all of spring training then spent the first two weeks of April on the disabled list with a slow-to-heal right Achilles strain it was reasonable to doubt how many games the 37-year-old slugger would be able to play. If Vegas oddsmakers had set a line it probably would've been no more than 100 and only a sucker would have bet the over.

Even the Red Sox insured themselves against an Ortiz breakdown. Upon re-signing their franchise icon last November to a two-year extension they included a clause that would hike his 2014 salary from $11 million to $15 million if he spent fewer than 20 days on the disabled list with the Achilles injury. Ortiz clinched that raise this week.

"I was supposed to play 20-30 games less than what I have but I don't buy into that" Ortiz said Wednesday before the Sox wrapped up their two-game series against the Colorado Rockies. "It feels fine you know? It's pretty much one day you get a little sore one day it goes away and you feel better. It depends on how much you run the day before. But we're playing interleague in September towards the end of the season and I played yesterday and I'm playing again today. It's not something that worries me."

The Red Sox aren't worried either. While manager John Farrell has taken great care to rest first baseman Mike Napoli who is dealing with a painful bout of plantar fasciitis in his left foot Ortiz has gotten back-to-back games off only once since he came off the disabled list on April 20 both of which came last month during an interleague series in Los Angeles. And since then he has played 26 consecutive games.

"John's been really good about asking me (to take a day off) but once I'm in I'm in man" Ortiz said. "I don't care about anything but playing and trying to win ballgames. Until I stop playing you're not going to get me out of there."

Speaking of which retiring Rockies icon Todd Helton was honored Wednesday night before playing his final game at Coors Field. Two weeks ago the Sox paid tribute to Yankees closer Mariano Rivera whose legendary career is down to a few final games. - See more at: http://bostonherald.com/sports/red_sox_mlb/clubhouse_insider/2013/09/surprise_david_ortiz_has_been_mr_durability_for_red_sox#sthash.f1dubQlB.dpuf
