I'm just worried people are going to walk out midseason. ...Thirty owners need to be answering that because you have one of the best players in the game that needs a job and no one is signing him.You've got 30 owners who have a sabermetric box that will sign players when they were in that box. They don't take any intangibles or anything else into play and that's a sad thing.Chicago Cubs reliever Brad Brach shared similar comments with reporters Friday, via NBC Sports Chicago's Tony Andracki:"I really don't know [what to make of the state of free agency].We talked to certain teams and they told us, 'We have an algorithm and here's where you fall in that scale.' It's just kinda weird that all offers are the same that come around the same time and everybody tells you there's an algorithm, but you figure teams have different ones Chris Owings Jersey , but I don't know."The state of MLB free agency has become a hot topic as marquee players have waited months into the offseason before signing contracts over the past two years.Yu Darvish, J.D. Martinez and Eric Hosmer went through the winter last year before agreeing to deals in February.With all 30 teams reporting to spring training this week, Bryce Harper, Manny Machado, Craig Kimbrel and Dallas Keuchel are among the best free agents still available.Houston Astros ace Justin Verlander vented his frustration at the pace of free agency onTwitterthis week."System is broken," he wrote. "They blame 'rebuilding' but that's BS. You're telling me you couldn't sign Bryce or Manny for 10 years and go from there? Seems like a good place to start a rebuild to me. [Age] 26-36 is a great performance window too."Per ESPN.com'sJeff Passan, 18 out of 30 MLB teams are at least $50 million below the $206 million luxury-tax threshold.There is still time for for players like Harper Archie Bradley Jersey , Machado, Kimbrel and Keuchel to negotiate deals that will make them happy.

He's posted a .352/.448/.682 triple-slash line with seven home runs in 88 at-bats after winning the Home Run Derby.His track record includes an NL MVP Award for the 2015 season and six All-Star selections, which will make him a coveted commodity this winter.Although Harper hasn't discussed his potential suitors, the slugger acknowledged last month that he could leave the Nats."It's always a possibility. Everyone knew that at the beginning of the year鈥攖his could possibly be my last year in D.C," hetold reporters. "There's no elephant in the room. Everybody knows that's a possibility."Choosing to leave Washington to join Philadelphia, a club the Nationals will likely be battling atop the NL East for the foreseeable future, would be a bold move Luis Gonzalez Jersey , not to mention make him public enemy No. 1 among baseball fans in the nation's capital.The Phillies have turned the corner in their rebuilding efforts on the strength of their pitching staff. Their lineup still needs work, however, as evidenced by ranking 20th in runs scored this season.Harper would provide a major boost should he choose Philly before the 2019 campaign.
