Ortiz will be team's seventh to hold the job in last decade.

Hitting coaches have become the disposable part of coaching staffs.

Don't like the way the club is going? Change the hitting coach. Depending upon staff decisions, as many as 16 teams could begin next season with a new hitting coach.

The Rangers belong to the group. They brought in Luis Ortiz to replace Anthony Iapoce, who went to the Chicago Cubs to replace Chili Davis.

A new hitting coach has become commonplace for the Rangers. Ortiz will be their seventh hitting coach since opening day 2009. Only Miami, with eight, will have had more hitting coaches in that span.

General manager Jon Daniels said he could not determine what impact the turnover has had on the offense. The constant change is not by design.

"We want to have stability and ability,'' Daniels said. "I'm aware we haven't had enough stability. Our intent with Luis is that we will have that''

A look at how the Rangers have gone from Rudy Jaramillo to Luis Ortiz at hitting coach:

Jaramillo ended a 15-year stay with the Rangers after the 2009 season. He turned down the club's offer of a one-year contract to take a three-year, $2.4 million deal with the Chicago Cubs.

During Jaramillo's tenure, Rangers hitters won four Most Valuable Player awards, three home run titles, one batting championship and 17 Silver Sluggers. The Rangers scored more than 800 runs in 13 consecutive seasons.

"I was hopeful that he would accept our offer,'' Daniels said at the time. "But I understand that he has put himself in a position that everyone in the game hopes to achieve, where you have options.''

Former Colorado manager Clint Hurdle arrived in 2010. Hurdle put more emphasis on the approach to hitting than the mechanics. Having good at-bats became the club mantra. The on-base percentage jumped from .320 a year earlier to .338.

Hurdle also became a booming presence in the clubhouse. He departed after one season to become manager with Pittsburgh.

"Clint was a great fit for the club and added a lot to the group,'' Daniels said when Hurdle accepted the Pirates' offer.

Thad Bosley did not make it to the All-Star break in 2011. The Rangers, citing communication gaps with key players such as Josh Hamilton, fired Bosley after only 62 games.

Bosley was the polar opposite of his predecessor. Hurdle was an energetic extrovert, always available to the hitters. Bosley was more of an introvert who kept a distance from the group.

"Sometimes the best-credentialed person and the best organization don't line up,'' Daniels said after dismissing Bosley. "We felt that was the case here.''

Scott Coolbaugh took on the difficult task of coming out of the minor league system to soothe the situation after Bosley. Coolbaugh succeeded.

In 2011, the Rangers finished third in the American League for runs per game at 5.28. They led the AL at 4.99 runs per game in 2012.

That was not enough. The Rangers, who collapsed in the finals days of the 2012 season, quickly moved to bring in Dave Magadan after Boston dumped him. Coolbaugh returned to a minor league position.

"We were not going to make a change unless we found somebody that was the perfect fit,'' Daniels said in explaining the move.

Magadan dealt with a changing roster that lost much of its punch.

Hamilton jumped to the Los Angeles Angels after the 2012 season as a free agent. Nelson Cruz missed 50 games in the second half of the 2013 season for his involvement in the Biogenesis scandal. Prince Fielder appeared in only 42 games in 2014 because of a neck injury.

The result was an offense that drifted toward the middle of the pack. In three seasons with Magadan, the Rangers had only a .400 slugging percentage.

Magadan and manager Jeff Banister did not click in one season together. Magadan departed after the 2015 season by "mutual decision,'' the Rangers said.

Anthony Iapoce took on a tough assignment in his first major league job. He inherited a collection of inexperienced and strikeout-prone hitters.

In three seasons with Iapoce, the Rangers averaged 8.64 strikeouts per game. They also hit 646 homers.

Iapoce stressed the "don't try to be a hero'' approach with two strikes in a count and focus on putting the ball in play. The hitters had difficulty putting that into practice. During Iapoce's three seasons, the Rangers hit .163 with two strikes in a count, third-lowest average in the majors.

When the Rangers could not guarantee Iapoce a spot on their next manager's staff, he took the sure thing of the Cubs' offer. That opened the door for Luis Ortiz, who like Iapoce will be a first-time major league hitting coach. How long will he stay?
