Rex Tillerson could be on  his  way to serving one of the shortest tenures of any Secretary of State in U.S. history.
âThere are no personnel announcements at this time â White House spokesman Sarah Huckabee Sanders said in a statement. â Secretary Tillerson  continues to lead the State Department and the entire cabinet is focused on completing this incredibly successful first year of President Trumpâs administration.â
âHeâs here.  Rex  is here â he said.
If  Tillerson  leaves in the next few months   he  would likely be viewed as one of the most underperforming secretaries of State in U.S. history with one of the shortest tenures to boot  say experts on American foreign policy.
âIt will ratify what is emerging as almost a consensus view that  Rex Tillerson  was the worst Secretary of State in modern time â said Paul Musgrave  a political science professor at the University of Massachusetts-Amherst who studies American foreign policy. âI actually think there is a good case to be made  ever.â
If  Tillerson  leaves in the next few weeks   he  will have served for roughly a year  inordinately short for a first-term Secretary of State in the modern era. The last three first-term secretaries of State â Warren Christopher  Colin Powell and Hillary Clinton â all remained in their posts for the entire term.
Aside from his short time in office   Tillerson  has little to show as accomplishments.

 Former first lady Michelle Obama  had a busy schedule during  her  years in the White House.
To make sure  her  personal life didn't get the short end of the stick   Obama  would plan out  her  year  adding date nights  vacations and even workouts  before signing on to any meetings or events.
"Oftentimes we don't do that as professionals  " Obama  said. "We schedule work before we schedule us."
 Former first lady Michelle Obama   speaking at Klick Health's Muse event in New York  said that was especially challenging after uprooting  her  family while  her  children were young to move to the White House.
"What we learned we had to do is start prioritizing us alongside â and often before â the work "  Obama  said.
"Oftentimes we don't do that as professionals. We schedule work before we schedule us "  Obama  said. But it doesn't have to be that way  she said. "The truth is even when you schedule your family  there's still plenty of time for work. But we don't plan like that."
"We always scheduled family dinners. He was always home in time to sit down for that family dinner "  Obama  said. "We had our regular vacations and Barack never missed a parent-teacher conference."

CHICAGO â Dusty Baker had a long talk with  Trea Turner  Tuesday morning before Game 4 of the National League Division Series between the Nationals and Cubs was rained out. The conversation with his struggling 24-year-old shortstop veered into a history lesson. Baker told him of the time Orlando Cepeda  then the MVP  struggled in the playoffs. He recalled Dave Winfield  another Hall of Famer  once had a terrible World Series. He told him of his personal struggles  of the time he hurt his hand in a fight before the 1981 World Series  couldnât swing a bat  and played anyway.
 Turner  isnât a Hall of Famer or even an all-star yet  but Bakerâs impetus for a chat is clear:  Turner  is the Nationalsâ energizer bunny and  his  struggles are crippling their offense. The Nationals hoped  Turner âs speed would disrupt the Cubs  who have a couple of pitchers notorious for their inability to control the running game. But  Turner  hasnât reached base in the playoffs yet. Through three NLDS games   he âs 0 for 12 with five strikeouts  including one with the bases loaded in Game 2. As  Turner  has said  you canât steal first base.  His  game-changing speed has been wasted.
âI havenât been nervous for a pitch this series â  Turner  said. âIâm focusing on ways to contribute to the team. Play some defense. If I can get on base  thatâd be great  but I havenât so I got to focus on other things and focus on my teammates  be a good teammate and hopefully we can turn this thing around.â
After Game 3 Monday   Turner  said  he âs made small adjustments âhere and thereâ at the plate in the series to break through and put  his  speed to use.  He  nearly did in  his  final at-bat in the eighth inning Monday  but Cubs second baseman Ben Zobrist made a diving stop on a groundball 79 mph off Turnerâs bat.
âThings still gotta go your way  â Turner  said. âYou still gotta find holes. Even if you hit the ball hard  you got to find the holes. Things arenât going my way.â
If the lineup Baker unveiled for Game 4 Tuesday before it was postponed is any indication   Turner  will have another chance atop the lineup again Wednesday against Jake Arrieta  who couldnât contain  Turner  when  they  clashed in June in Washington.  Turner  singled in  his  first plate appearance and walked in  his  second against Arrieta. Each time  he  promptly stole second and third base for four steals in three innings. Arrieta would allow six runs (five earned) and walk six batters in just four innings.
After the game  Cubs catcher Miguel Montero criticized Arrieta  whose delivery makes him susceptible to base stealers  for his inability to neutralize  Turner  on the base paths. Arrieta agreed with Monteroâs assessment  but Montero was designated for assignment anyway. So Montero wonât catch Wednesday. Itâll be Willson Contreras  who boasts one of the strongest arms behind the plate in baseball and picked  Turner  off first base in the first game of that four-game series back in June.
But base runners  Baker always says  steal bases off pitchers  not catchers.  Turner  could wreak havoc again and spark a Nationals offense hitting .121 through three games and on the brink of elimination.  He  just needs to get on base first.
