NEW YORK (93-7 The FAN/AP) — Baseball players and owners signed an agreement for a new labor contract Tuesday, a deal that starts blood testing on human growth hormone and expands the playoffs to 10 teams by 2013.

The five-year deal collective bargaining agreement makes changes owners hope will increase competitive balance by pressuring large-market teams to rein in spending on amateur draft picks and international signings.

At a time when the NBA season is threatened by a lockout and NFL preseason was disrupted by labor strife, it ensures baseball will have 21 consecutive years of labor peace since the end of the 1994-95 strike.

“Nobody back in the ’70s, ’80s and early ’90s, 1994, would ever believe that we would have 21 years of labor peace,” baseball commissioner Bud Selig said.

The deal, which still must be ratified by the players and owners, is the first contract since Michael Weiner replaced Donald Fehr as union leader last year.

With the agreement, baseball became the first of the major North American professional leagues to agree to blood testing for HGH. An initial positive test for HGH would result in a 50-game suspension, the same as a first positive urine test for a performance-enhancing substance.

As for the playoffs, there will be an additional two teams starting in 2012 or 2013 that will give baseball 10 of 30 clubs in the postseason. In the NFL, 12 of 32 teams make the playoffs. In the NBA and NHL, 16 of 30 advance.

The two wild cards in each league — the non-first place teams with the best records — will meet in a one-game playoff, and the winners will move on to the division series.

This agreement also calls for the Houston Astros to switch from the NL Central to the AL West in 2013, leaving each league with three five-team divisions. It’s baseball’s first realignment since the Milwaukee Brewers went to the NL after the 1997 season.

On the economics, the threshold for the luxury tax on payrolls will be left at $178 million each of the next two seasons, putting pressure on high-spending teams such as the New York Yankees, Boston Red Sox and Philadelphia Phillies not to raise their spending even more. The threshold rises to $189 million for 2014-16.

The minimum salary reaches the $500,000 mark in 2014, and then there will be cost-of-living increases in both of the following two years. There also will be a new “competitive balance lottery” that gives small-market teams extra selections in the amateur draft.

Major league free agent compensation will be completely revised in 2013, with a team having to offer its former players who became free agents the average of the top 125 contracts — currently about $12 million — to receive draft-pick compensation if a player signs with a new team. It eliminates the statistical formula that had been in place since the 1981 strike settlement.

In addition, the portion of players with 2-3 years of major league service who are eligible for salary arbitration will rise from 17 percent to 22 percent starting in 2013.

And there a new market disqualification test, preventing teams from large markets from receiving revenue-sharing proceeds — and lowering the amount the big teams pay as long as they stay under the payroll threshold.

Owners achieved their goal of reining in spending on amateur players coming to the major leagues. For high school and college players taken in the June amateur draft, there will be five bands of penalties, starting with a 75 percent tax on the amount 0-5 percent over a specified threshold for each team next year, based on its selection spot. For teams going 5-10 percent over, the tax will rise to 100 percent, and they will lose their next first-round draft pick. If a team goes more than 15 percent over, it could lose its following two first-round draft picks.

For international amateur signings from nations such as the Dominican Republic and Venezuela, a luxury tax will begin with the July 2012-June 2013 signing season.
